Append values from a data frame to a list created in for loop

Asked 2021-Sep-06 at 19:49

*Edit: Thanks to Martin and a little bit of time and attention, I was able to get the code where I needed it to be. Is it ugly? Yes, but it works in way that's useful to me now. Any tips on how to clean this up and make it more efficient would be super helpful.

Using the data frame trace_list, I'm trying to append the values from Title and Year to the output of each list in the for loop. The following code opens each state's PDF link on page 10, pulls the city data (which ranges from 1-12 cities). Clean/tidies the data, and stores it in a list to be bound after data from each PDF is collected. ~~Right now it only pulls the city name and a numerical value.~~

QUESTION

Separating values into existing column in R

Asked 2021-Jul-28 at 15:43

I'm tidying some data that I read into R from a PDF using tabulizer. Unfortunately some cells haven't been read properly. In column 9 (Split 5 at 37.1km) rows 3 and 4 contain information that should have ended up in column 10 (Final Time).

How do I separate that column (9) just for these rows and paste the necessary data into an already existing column (10)?

I know how to use tidyr::separate function but can't figure out how (an if) to apply it here. Any help and guidance will be appreciated.

PDF scraping: get company and subsidiaries tables

Asked 2021-May-26 at 06:59

I am trying to scrape this PDF containing information about company subsidiaries. I have seen many posts using the R package Tabulizer but this, unfortunately, doesn't work on my Mac for some reasons. As Tabulizer uses Java dependencies, I tried installing different versions of Java (6-13) and then reinstalling the packages, still no luck in getting this to work (what happens is when I run extract_tables the R session aborts).

I need to scrape the whole pdf from page 19 onwards and construct a table showing company names and their subsidiaries. In the pdf, names start with any letters/number/symbol, whereas subsidiaries start with either a single or double dot.

So I tried with pdftools and pdftables packages. The code below provides a table similar to the one on page 19:

Like @Justin Coco hinted, this was a lot of fun. The code ended up a bit more complex than I anticipated, but I think the result should be what you imagined.

I used pdf_data instead of pdf_text so I can work with the position of words.

trying to scrape from long PDF with different table formats

Asked 2021-Apr-29 at 19:46

I am trying to scrape from a 276-page PDF available here: https://www.acf.hhs.gov/sites/default/files/documents/ocse/fy_2018_annual_report.pdf

Not only is the document very long but it also has tables in different formats. I tried using the extract_tables() function in the tabulizer library. This successfully scrapes the data tables beginning on page 143 of the document but does not work for the tables on pages 18-75. Are these pages unscrapable? If so why?

I get error messages that say "more columns than column names" and "duplicate 'row.names' are not allowed"

As texts in pdf files are not stored in plain text format. It is generally hard to extract text from a pdf file. The following method provide an alternative method to extract the table from the pdf. It requires the pdftools and plyr package.

Scraping PDF in R with Nested Information

Asked 2021-Jan-20 at 21:51

I am attempting to scrape a rather difficult PDF in R using both pdftools::pdf_text and tabulizer::extract_tables. However, in my situation, neither of these seems to be too helpful based on the nature of the PDF. The PDF contains "nested" information, as shown in the picture.

What is the best way to approach this? Splitting by white space using stringr::str_split_fixed with n=3 gave me matrix, but it seems too difficult to create a regular expression to detect the information I want (only after the Description, and Incident Date/Time) within each column.

I'm attempting to install rJava as to use the package tabulizer. My steps so far has been to rund install.packages("rJava"), run Sys.setenv(JAVA_HOME="C:/Program Files/Java/jdk-15.0.1"), and then run library(rJava). When running the last command I first get a pop-up showing EXTPTR_PTR Entry Point for procedure not found (based on my hopeful translation), and then in console:

There was accidental breakage introduced by R 4.0.0 or R 4.0.1 which was fixed in R 4.0.2 and R 4.0.3. Are you by chance running 4.0.1? Upgrading would help.

The official word from one R Core member is to not use EXTPTR_PTR (see e.g. this list email). The current CRAN version of rJava should also be fine.

So in short: 'current' rJava with 'current' R should be fine.

Install tabulizer

tabulizer depends on rJava, which implies a system requirement for Java. This can be frustrating, especially on Windows. The preferred Windows workflow is to use Chocolatey to obtain, configure, and update Java. You need do this before installing rJava or attempting to use tabulizer. More on this and troubleshooting below.
